Vehicle control apparatus

A vehicle control apparatus comprising:

• first motor-generator means for driving at least one first wheel and for generating electricity from the first wheel;
• second motor-generator means for driving at least one second wheel that is not connected to the first motor-generator means and for generating electricity from the second wheel;
• and
• regenerative braking means for performing regenerative braking in which a first braking torque is applied to the first wheel by regeneratively operating the first motor-generator means while a second braking torque is applied to the second wheel by regeneratively operating the second motor-generator means,
• the regenerative braking means being configured and arranged for
• calculating an ideal front-rear wheel distribution ratio between the first braking torque applied to the first wheel and the second braking torque applied to the second wheel;
• calculating an allowance of the ideal front-rear wheel distribution ratio;
• and
• correcting the ideal front-rear wheel distribution ratio within a range of the distribution allowance to increase electric power generation efficiency of at least one of the first and second motor-generators.
